REGISTERING DEVICE.

Specification of Letters Patent.

Application filed October 18, 1917. Serial No. 197,294.

To all whom it may concern Be it known that I, A LBA DAVID REEsE, acitizen ofthe United States, residing at Bisbee, in the county ofCochise and State of Arizona, have invented certain new and usefulImprovements in Registering Devices; and I do declare the following tobe a full, clear, and exact description of the invention, such as willen able others skilled in the art to which it appertains to make and usethe same. This invention relates to certain new and useful improvementsin registering devices. The primary object of the invention is toprovide a device which is adapted to be placed in a mine or tunnel whereblasting is to be done, said device including registering mechanism anda member acted upon by the concussion of the air caused by the blast tooperate the registering mechanism.

Another object of this invention is to provide a device of thischaracter vhich will be comparatively simple, strong, durable andinexpensive in construction, efficient and reliable in operation, andwell adapted to the purpose for which it is designed. 1

Nith these and numerous features of construction, and the combinationand arrangement of parts as will be hereinafter fully described andclaimed.

In the accompanying drawings forming a" part of the application and inwhich similar reference characters are used to designate like partsthroughout the several views:

Figure 1 is an elevation of one side of a device constructed inaccordance with this invention, the door on this side of the de vicebeing shown open and in section;

Fig. 2 is a similar view of the other side of the device;

Fig. 3 is a horizontal sectional view through the device;

Fig. a is a longitudinal sectional view of the same; and

Fig. 5 is a vertical sectional view taken on the line 5-5 of Fig. 4.

Referring more particularly to the drawings, the numeral 1 designates asuitable base upon which .a housing or casing 2 is mounted. This housing2 is of rectangular shape in configuration and has its opposite sidesprovided with doors 3 so that access to the interior of the housing maybe obtained from either side.

Mounted within the housing 2 is a regis other objects in view, theinvention consists of certain novel 1 wound up by eted or otherwisesecured to the tering mechanism, the frame work of which mcludes a pairof side plates a. Mounted on the exterior side of one of the side plates4. in any suitable manner is a dial 5, the latter being provided with aseries of successive numbers as clearly shown by Fig. 2. EX- tendingthrough the central portion of the dial 5 and mounted in the side platest is a shaft 6 which carries a pointer 7 on its outer end and a pinion 8intermediate of its ends. The pointer 7 is designed to cooperate withthe g aduation on the dial 5.

Meshing with the pinion 8 is a gear wheel 9 carried by a shaft 10mounted between the plates 4. The shaft 10 also carries a suitablespring device 11 whereby motion may be imparted to the detent to behereinafter explained. The spring device may be a key 12 fixed to theshaft 10 and disposed on the exterior side of one of the side plates 4-.

The numeral 13 represents another shaft which is mounted between theplates 4 and which carries a pinion 14: meshing with the gear wheel 9.Carried also by the shaft 13 is an escape wheel 15, the latter beingengaged by a detent 16, formed at the inner end of an arm 17 which isfixed to a shaft 1.8 mounted between the side plates 4. The shaft 18also carries an arm 19 against which bears one end of a spring 20fastened to one of the plates 4.

The arm 17 extends through a slot or opening 21 arranged in the top ofthe housing to the exterior of the same. Rivouter end of this arm 17 isa blade 22, the latter being here shown in the form of a substantiallyoval shaped plate having its edges curved or dished outwardly.

The detent 16 is maintained in engagement with the escape wheel 15 tohold the registering mechanism normally inactive by the spring 20 andthe blade 22 is consequently held in one of its two positions by thesame means. Whenever the blade 22 is moved backwardly or to its otherposition, the detent will disengage the escape wheel 15 for a moment andpermit the spring means 11 to impart motion to the pointer 7. As soon asthe pressure is removed from the blade 22 the spring 20 will return theparts to their normal positions and again disengage the detent 16 fromthe escape wheel 15 and permit the pointer to be moved anotherpredetermined amount. The num- Patented Apr. so, 1918.

bers upon the dial are so spaced that the pointer will move from onenumber to an-r other when the plate 22 is moved from its normal to itsother position and then back again to its normal position.

The device is designed primarily for use as what may be termed a blastor explosive register, and obviously must be placed in the mine ortunnel where the blasting is to be done. Vhen a blast takes place theconcussion oil "the air caused by the blast will move the plate 22baclnvardly and set the registering device into operation. Every timethere is a blast, the registering device will operate and thus a numberof blasts will be registered.

By putting the device in a mine or tunnel where a number of blasts areto be set ofi' in succession, the number of blasts which actually firewill be registered and hence the many accidents which have heretofore occurred by drilling into missed holes will be lessened.

From the foregoing description taken in connection with the accompanyingdrawings, the construction, use and operation of the. device will bereadily understood without a more extended explanation.

As various changes in form, proportion, and in the minor details ofconstruction may be resorted to'without departing from the spirit of theinvention, it is to be understood that I do not wish to be limited tothe construction herein shown and described other than as claimed.

An explosion registering device comprisin a plate adapted to receivepower from the shocks resulting from explosions and to be moved towardone side by the power obtained from the shock-forces, a support, an armpivotally mounted on said support and extendil'ig approximatelyvertically therefrom and supporting said plate in approximately verticalposition and movable thereby and therewith to and from normal position,a registering mechanism, means constantly tending to drive saidregistering mechanism, a vdetent carried by said arm and normallyengaging with said registering mechanism to prevent untimely operationof the latter, and a second detent carried by said arm in position toengage with said registering mechanism and arrest movement of thelatter'after it has been released by the first said detent and therebyallowed to register a shock.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing wltnesses.
